Seems I'm not getting the writing to a txt file done.


Quote
oclvanitygen64.exe -v -F compressed -d 1 1EnJoy -o matches.txt
Prefix difficulty:            259627881 1EnJoy
Invalid character '-' in prefix '-o'
Invalid character '.' in prefix 'matches.txt'
Difficulty: 259627881

am I doing something wrong?


And is there a way I can get both my GPU's active in searching? Currently only 1 GPU seems to get busy searching.

Try oclvanitygen64.exe -v -F compressed -d 1 -o matches.txt 1EnJoy

You would need to run two copies of oclvanitygen64.exe, one using -d 1 and the other using -d 2. (Or whatever numbers correspond to your 2 GPUs.)

Thanks for the help, saving to a file is working.

Same I can't get 2 GPU's to work on the same job, would cut the time in finding an address in half ;-)

You Can. Try something like this: oclvanitygen -D 0:0 -D 0:1 -v -F compressed -d 1 -o matches.txt 1EnJoy

For me it's working. Both cards are working and the hashrate is the sum of them.

From http://lifeboat.com/ex/press.releases.bitcoins.hundred.thousand.dollars :

"to give back to the bitcoin community, Lifeboat Foundation has created the first Windows version of oclvanitygen in the world that runs well on high-end AMD cards. (Our version runs nearly four times as fast as the old version!) We also added support for compressed keys as well. You can download it for free at http://lifeboat.com/oclvanitygen and can learn more about what we did on GitHub at https://github.com/samr7/vanitygen/issues/19. oclvanitygen is used to create vanity bitcoin addresses such as our bitcoin address 1Lifeboatu7Y9YqKQRcXfjWYJdXog9CS7r that begins with 1Lifeboat. PGP signature for program is here."

Note that a high-end AMD card is defined as an AMD Radeon 7xxx GPU or greater. If you have a slower card then you can just download oclvanitygen as described at https://en.bitcoin.it/wiki/Vanitygen And if you need a Linux fix for high-end AMD cards, read https://github.com/samr7/vanitygen/issues/19 to learn how to fix oclvanitygen.

Finally, oclvanitygen, no matter what the operating system, hates the latest AMD Catalyst drivers. So if, for example, you are running Catalyst 13.9, you would also want to use the AMD APP SDK Runtime from Catalyst 12.10. (So all your Catalyst drivers would be brand new except for the SDK Runtime.)

This is beyond great! Thank you for your hard work and efforts!

If you are asking how long of a word you can specify and get, at Lifeboat we have gotten 1LifeboatVPg24QghZ73Dzrx8AxcJLCnoA and we use the phrase "Become a Lifeboat VIP and donate to bitcoin address 1LifeboatVPg24QghZ73Dzrx8AxcJLCnoA". So 1Lifeboat was specified, we got many results, and are currently using a 1LifeboatVP match which is pretty cool.

That's not what he's asking.

The length depends on how many case insensitive options there are for each word, along with the length of words and video card RAM. Case insensitive searches are unrolled into all possible matches; they consume the same resources as specifying all 100 or 1000 matching addresses.

I have a 12-13 character long word list, and case insensitive searches on it were limited to about 4000 entries. Shorter words can be tens of thousands in a list.

I thought I had managed to build it, and ended up with a (32bit) binary, but it just wouldn't run (Windows error saying "The application was unable to start correctly (0xc000007b). Click OK to close the application"). I had some issues building libcurl, I think that's where it went wrong. The readme doesn't mention it and it's just assumed in the makefile... I haven't dabbled in that area of programming in a number years, so I could be forgetting something pretty simple.

I had to lol at this. First and foremost unless the program was coded to work WITHOUT arguments it won't close. The program EXPECTS arguments, you are not giving it any, so it just exits. This is stuff on a basic level.
